Service Context

Different transit services call for different facilities. While street design practice has historically focused on motor vehicle movement and has treated transit capacity as primarily influenced by stop design, street design processes are increasingly recognizing that key transit lines—those with higher ridership, higher frequency, and more potential for growth—both need and justify greater accommodation than lower-ridership routes.

Designing for the type and frequency of transit service on a street means providing transit with priority treatments and the space necessary to perform at a high level. Whether a route uses bus, light rail, or streetcar, service decisions in an urban transit network are made based on a complex combination of capacity, reliability, comfort, and the need to accommodate passengers in a network. Some projects involve a simultaneous change in transit service on a street along with transit prioritization or streetscape investments, but all street design projects have a service context.

This section provides designers and planners with a basis of discussion of the needs of transit, by linking specific design elements and comprehensive street designs, found later in the Guide, with concepts of transit service frequency and the type of transit route supported by a street.

Transit Route Types

Robust evidence-based service planning using realistic data can identify new service and growth opportunities, especially opportunities to add rapid routes. These can be supported by street design to create broader transit benefits.

Transit Frequency & Volume

Street design has an interactive effect on transit frequency, both supporting transit at different volumes, and attracting passengers to different degrees.
